Transcatheter aortic valve implantation (TAVI)

Transcatheter aortic valve implantation (TAVI) is performed either from the femoral artery (transfemorally) at the top of the leg, or through a small incision in the chest – transapical (minimally invasive heart surgery). At present, the technique of percutaneous aortic valve replacement (using mainly Medtronic CoreValve and Edwards Sapien) can only be offered to patients who cannot be operated or they are of very high risk for conventional heart surgery. Over 30,000 operation of this kind have already been performed worldwide today.

When transcatheter aortic valve implantation (TAVI) is performed transfemorally, via the groin, a local anesthetic is used to numb the area around the artery in order to insert a special catheter. Once inside the artery, the catheter is advanced from the groin to the aortic valve of the heart. This catheter carries an expanding valve armed with a specially designed balloon. The patient usually leaves the hospital within 2-3 days after surgery.

When we are replacing the aortic valve through a small incision in the chest – transapically, a general anesthetic is given to the patient. After a small incision has been made to the left side of the chest, a special catheter is advanced from the apex of the heart to the aortic valve. This catheter carries an expanding valve armed onto a special balloon. The patient usually leaves the hospital within 3-5 days after surgery.

Percutaneous mitral valve repair

Percutaneous mitral valve repair can be achieved by various techniques.

Percutaneous mitral valve repair using the MitraClip ® device has shown the best results to date and requires only local anesthesia. We promote a special catheter from the femoral vein (leg) to the mitral valve. Then, by manipulating the catheter we deploy the MitraClip ® device and the valve is repaired (variety of the Alfieri technique). After the mitral valve is repaired, the patient returns to the high dependency area for observation. The patient leaves the hospital the next day. At present, the technique of percutaneous mitral valve repair is intended only for patients who cannot be operated or they are of very high risk for conventional heart surgery.

Athens Heart Institute offers the only Heart Team approach in the treatment of transcatheter valve surgery. Our team members have been trained in the technique in world-renowned medical centers in the USA.  We have performed over 400 such operations Cornell Medical Center and now we can offer this treatment to Greek patients from all over the country. Our success rate approaches 99% in selected patients.
